fuel injection problem
 

having problems with fuel injection system, its on a 3.0d it had new injector rails and pump 3months ago under warranty but still having problems when put on diag fault was low fuel pressure but dealer says pressure was normal. then yesterday it just stopped, it restarted but now has no power on hills any ideas.

The parts/labor will still be under warranty so your first move should be to get it looked at by the same place that put the parts in.....
